Input needed - Timing curve - Terminator X

Well sounds like you're on the right track and the car is running OK so I wouldn't be too concerned with screwing things up. You can always go back to a known good tune if you find something isn't working.

The Hyperspark obviously does not have a provision for vacuum advance so you have to make adjustments to whatever cells you select in the table. I found the image I put up of how the table areas are delineated was really helpful for that, kind of took the guess work out of it.

Not a ton of EFI guys here so I'd consider joining the Holley forums and see if you can get a little more detailed help over there.
